Auto-wheel’s pH neutral formulation reacts with the oxidising surface of the metallic particle rendering it water soluble, the rapid removal of this microscopically rusted surface reduces the embedded particle size and releases it from the surface, unlike acids this method is harmless to the wheel’s finish and in fact so fast it cleans more effectively – the reaction is seen by a rapid colour change from clear to deep red, after which a simply hose or rinse leaves the wheel spotless. In severe cases a brush can be used to assist the process.
I’ve used this many times before but picked some up from Roll Up N Shine. Excellent click and collect procedure during COVID-19!
Simply spray on after pressure washing the alloys and watch as the spray reacts with all of the remaining fallout particles and bleeds down. Most of the time you don’t even need to agitate – just leave for a few minutes and then rinse! Amazing stuff.
